No'Dra'w'ing'. Original application 'filed August 27, 1924;8er1a1 No. 734,524, and in Great Britain septemrber 22, 1923. Divided and this application flied Am- 1 17, I925. Serial 1%. 2 3,966;

This invention has for its object to predues impacted date-maveeffects in row the following ingredients in the following approximate proportions: r0100 lbs. of Paris white (sifted and dry), 4 to 6 lbs. of stucco, 7 to' 'lbs; lithopone, 6' to 8' lbs. hard and soft strong-gums in suitable proper tions such as 41 lbs. of gum arabic to 1 A;

lbs. of gum tr'agacanth, each dissolved in just sufficient water, lbs; of cream of tartar and 12 lbs: offwat'r re mixed and finely groundin a roller mill or the like. In a separate vessel I'm'iX 5% lbs. of finely ground zinc oxide with 5% lbs. of linseed "oil (fire-boiled), also known as Dutch stand oil, 2 lbs. paraffin 011:, 2 lbs; of pale boiled linseed oil with a suitable drier-L I then incorporate the whol together by thorough mixing and the material is then ready for use. i

The improved separatin paint can be plied toany dry surf'acew ich has been previously rendered" non-absorbent such by means of one or two coats of-ordtnar-y oilpaint, and can: be applied" over a dry oilpainted surface of any colour, without the previous application of an undercoat of special composition. The separation of my improved paint on the surface to which it is applied, reveals the ground colour as part of the finish, thus giving a two colour effect when applied to a plain painted surface.

If higher relief is desired, two coats of my improved separating paint may be applied to the surface, us ng an intermediate coat of oil paint.

The decorative effects in low colour relief obtained by my improved separating paint can be glazed, scumbled or wiped. Various irregular designs in relief, such as loops, globules and other markings, can be obtained by varying the relative proportion of water and oil in my improved separating paint according to the result desired, Should" r-egu l-" ity of the surface design be desired, the surface bestippled slightly.

The" improved separating paint be applied to thesrirf'a'ceby means of a brush and the dc "orative surface so produced may be scuifibl'ed with metallic err-eats by the use Of- Q'OlCl OI" (itl lef' blOfiZeS ill aI iy Suitable medium. H

The improved separating paint can be tinted with oil colour or other colouring substances "or it may be glazed over with suitable colours, seuinbled and wiped in the usual manner according to the colour scheme 1'11 ii-S l v A gold, bronze or like background ean be imparted to the decorative design by rubhing lightly over the following day; or later, according to temperature, with a flannel or other suitable pad dipped in the gold, bronze or like powder. The gold, bronze or like background is produced "by reason of the fact that the raised arts of the design produced by my'improved separating paint dry at a quicker rate than other parts and the 1 powder, when rubbed over the design, adheres to the slower" drying -part'sof the design resulting a metal ground with a pat tern ei'ther white orothert'vis'e according to whether the improved separating paint is ginted or not before application to the surace;

To produce a scumble glaze I' prefer to use a composition of pale varnish, bleached boiled oil and parafiin in equal quantities with a suitable liquid-drier and the necessary pigments. This gives a refined degree of colour and protects the bronze portion from atmospheric influences. Y

An effect of free-hand design of a serpentine or other regular or irregular character may be obtained by first applying my improved separating paint to a dry oil-painted ground'and, immediately thereafter, before the first coat is dry, applying thinned-out separating paint with a brush or the like in a series of S-shapes, loops or other regular or irregular figures, the thinning-out of the separating paint being effected by the addition of more water. The thinner paint separates with more energy and produces a non-repeating pattern of serpentine or other regular or irregular character wherein the pattern produced varies with each 8- shape or other figure adopted in the applicasuitable pigment. WVhile the glaze is wet, it-

may be combed with a piece of fielt or like material notched on edge and drawn perpendicularly over the work, giving a jasp effect to the background portion of the design.

An irregular non-repeating tree or foliage pattern may be executed with my improved separating paint by applying the brushwork in slightly overlapping form, such as criss-cross-wise or after the manner of overlapping herring-bone pattern. When dry, a coat of ordinary black or other dark oil paint is applied over the separating paint which, when dry, may be given one coat of varnish. After drying, the surface may be scumbled with a gold paint scumble or any other suitable scumble which, being .wiped into the loops formed by the separation of the paint on the fiat surface, gives the effect of overhanging foliage, which can be further enhanced by the use of green, brown or other glazes.

Claims:

1. The method of producing an improved decorative effect in low colour relief upon a surface, which consists in applying a paint composed of Paris white, stucco, lithopone, gums, cream of tartar and water incorporated with zinc oxide, Dutch stand oil, paraffin oil, boiled linseed oil and a drying agent directly to the surface when the surface is in a dry state.

2. The method of producing an improved decorative effect in low colour relief upon a surface, which consists in rendering the surface non-absorbent by the application of an oil paint, allowing the surface so painted to dry and thereafter directly applying a paint composed of Paris white, stucco, litho pone, gums, cream of tartar and water incorporated with zinc oxide, Dutch stand oil, paraffin oil, boiled linseed oil and a drying agent to the oil painted surface.

8. The method of producing an improved decorative effect in low colour relief upon a surface, which consists in applying a paint composed of Paris white, stucco, lithopone, gums, cream of tartar and Water incorporated with zinc oxide, Dutch stand oil, paraffin oil, boiled linseed oil and a drying agent directly to the surface when the surface is in a dry state and thereafter rubbing over the surface with a decorative metallic powder.

l. The method of producing an improved decorative effect in low colour relief upon a surface, which consists applying a paintcomposed of Paris white, stucco, lithopone, gums, cream of tartar and water incorporated with zinc oxide, Dutch stand oil, paraffin oil, boiled linseed oil and a drying agent directly to the urface when the surface is in a dry state, whereby the paint separates, forming irregular markings, and varying the markings by regulating the relative proportion of water and oil in the paint.

5. The method of producing an improved decorative effect in low colour relief upon a surface, which consists in applying a paint composed of Paris white, stucco, lithopone, gums, cream of tartar and water incorporated with zinc oxide, Dutch stand oil, paraffin oil, boiled linseed oil and a drying agent directly to the surface when the surface is in a dry state and finally treating the surface with a scumble glaze consisting of pale varnish, bleached boiled oil, paraffin, a liquid drying agent and pigments.

6. The method of producing an improved decorative effect in low colour relief upon a surface,wvhich consists in applying a paint composedof Paris white, stucco, lithopone, gums, cream of tartar and water incorporated with zinc oxide, Dutch stand oil, paraffin oil, boiled linseed oil and a drying agent directly to the surface when the surface is in a dry state and finally treating the surface with a scumble glaze consisting of pale varnish, bleached boiled oil and paraffin in equal quantities with a liquid drying agent,

or pigments.
